how to refresh the dataset

Question

Hello :) I have a combobox which is filled with a fillbytoolstrip but before filling the cb i want to refresh the dataset, how can i do that?

private void adaugaContract_Load(object sender, EventArgs e)

        {

            // TODO: This line of code loads data into the 'asigurariDataSet.client' table. You can move, or remove it, as needed.

            this.clientTableAdapter.Fill(this.asigurariDataSet.client);

            fillBy2ToolStripButton_Click(sender, e);

        }

        private void fillBy2ToolStripButton_Click(object sender, EventArgs e)

        {

            try

            {

                this.clientTableAdapter.FillBy2(this.asigurariDataSet.client);

            }

            catch (System.Exception ex)

            {

                System.Windows.Forms.MessageBox.Show(ex.Message);

            }

        }
